Cloth: revert back to using bm_prev

This is important to ensure correct collisions and other stuff, maybe there is a more effictient way without bm_prev, need to check later.

Cloth: prevent unnecessary copy of vertices

Cloth: intial steps towards preserving original mesh data

Cloth: different seam or boundary detection

Cloth: fix some bugs in a hacky way, must see again later

Cloth: switch to cpp style while finding bad_edges

Cloth: remove unnecessary code

Cloth: fix bug while reindexing vertices

Ensure it uses the ClothVertMap size while allocating memory for cloth->verts.

Cloth: stop using bm_prev

Cloth: nearly completed transition to using ClothVertMap

Cloth: initial steps towards creating a mapping between BMVert* and ClothVertex for improving efficiency

Cloth: better handling of sizing

Cloth: better flip edges implementation

Cloth: fix updating active faces after fixing mesh in collapse edges

Cloth: better handling of split_edges()

Cloth: better edge_size() when edge is given

Cloth: fixed bug in cloth_remeshing_edge_face_pair()

Cloth: stop using uv_of_vert() to increase uv finding accuracy

Cloth: edge_opposite_vert() now returns the vertex uv if needed

Cloth: edge_vert() now returns the vertex uv if needed
